Tools for spatio-temporal disaggregation of areal data across multiple time points, including support for changing polygon boundaries. Implements methods for spatially aggregated log-Gaussian Cox process models with changing areal boundaries as described in Ripstein, Brown and Stafford (2026) "Spatio-Temporal Disaggregation with Changing Areal Boundaries" <doi:10.48550/arXiv.2606.25074>. Combines polygon-level observations, population rasters and optional covariate rasters to infer fine-scale spatial fields over time. Models can be efficiently fit using 'TMB' (Template Model Builder) and adaptive Gauss-Hermite quadrature for fast approximate inference or via 'tmbstan' for MCMC.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)

install.packages("DAST")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

pak::pak("nripstein/DAST")

Development version from nripstein/DAST. Requires the pak package.

Release

# one-time r2u setup for Ubuntu (noble)

curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash

# then install

sudo apt install r-cran-dast

Fast Ubuntu binaries via r2u (no compilation). Run the setup once per machine.

bspm (used by r2u) also needs make: sudo apt install make

sudo dnf copr enable iucar/cran

sudo dnf install R-CRAN-DAST

RPMs from the iucar/cran COPR, rebuilt from CRAN.
